I honestly felt like everyone from Barda, to Orion, to Grammy were all acting out of character to some degree or another. As for the anti-life equation, I can only remember in the Cartoon Network's Justice League Unlimited that Darkseid got it.
Look at how the details change. Remember, part of Darksied's Anti-Life thing is that they create a "life where one would wish for death." Everything is off because we aren't quite sure if this is reality or this is a manipulation of Darksied's Anti-Life equation.
What is so heart-wrenching is the more out of control its getting, the more I think Scott is succumbing to the illusion of the Anti-Life equation.
